Aiming for Carbon Neutrality

SMK has set medium- to long-term targets for Scope 1 and 2 emissions, aiming to achieve carbon neutrality by FY2045.

Carbon Neutral Target
Medium-term Target Long-term Target
FY2030: Reduce CO2 total emissions by 40% from FY2020 FY2045: Achieve carbon neutrality

In addition, in line with the Electrical and Electronics Industry’s Carbon Neutrality Action Plan, we are working to improve energy efficiency in manufacturing processes, targeting an average annual improvement of 1% or more in energy consumption per unit of production value.
Regarding Scope 3 emissions, we are expanding the collection of primary data and will strengthen collaboration with suppliers to promote reduction initiatives.

Key initiatives

  • Upgrade to energy-saving facilities
  • Consideration of the expansion of renewable energy
  • Consideration of purchasing certificates or carbon credits

Progress in FY2025

CO2 emissions reduced by 53% from FY2020.
On track to achieve the medium-term target.

Energy and Resource Saving Results

Preventing global warming is considered an important management issue, and efforts are being made to improve energy efficiency.
Additionally, initiatives are in place to reduce waste discharge and achieve zero emissions (zero landfill waste disposal), aiming for the effective use of resources.

  • Purchased electricity (Overseas): Factors from IEA Emisson Factor 2021 are used.
  • Fuel: Factors based on the Ministry of the Environment's "Greenhouse Gas Emissions Calculation, Reporting, and Publication System" are used.
  • Past results have been revised due to the update of CO2 emission factors.

Use of renewable energy:

In fiscal 2025, the Philippines plant switched its purchased electricity to renewable energy derived from geothermal power generation.
Combined with electricity generated by on-site solar power systems for self-consumption, the plant achieved zero Scope 2 emissions, following the achievement previously realized by SMK America (San Diego H.Q.).
The installation of solar power generation systems at production sites has been completed at all locations where installation is feasible.
For the remaining sites, we are considering the introduction of renewable electricity as well as the utilization of environmental attributes, such as non-fossil certificates and carbon credits, taking into account local regulations and electricity supply conditions.

SMK Eco Products

Since FY2012, we have established internal criteria for SMK Eco Products.
Eco products consist of "Eco-contributing products," which are classified by the end market of customer products, and "Eco-friendly design products," which are evaluated based on the level of environmentally friendly design.

Deatails
SMK Eco Products Eco-contributing products SMK products used in products for environmental markets as defined by internal standards
Eco-friendly design products SMK products that meet internal standards for energy conservation and higher efficiency, resource conservation, environmental protection and eco-friendliness, and reduced load on manufacturing processes

Percentage of sales of Eco Products

SMK Eco products =Eco-contributing products plus Eco-friendly design products
(If both are applicable, they will be counted unduplicated.)
